Nonlinear heat capacity and viscosity behavior as functions of concentration has been examined at the molecular level. The collective modes leading to enhancement of potential energy fluctuation and as consequence to heat capacity maximum has been found and discussed. (C) 2003 Elsevier B.V. All rights reserved.
